摘要
依靠井下节流嘴来实现井筒节流降压、地温加热,有效地防止了天然气水合物的形成,并简化了地面工艺流程、降低了投资。由于地面流程的简化,应用井下节流器的气井多数采用总体计量与轮换计量,给单井的动态分析带来了困难。建立井下节流气井产量计算方法,编制相应的程序,通过现场应用表明,建立的计算方法可行,对井下有节流器的气井进行产量估算具有一定指导意义。
Using downhole throttling nozzle to reduce pressure and to utilize geothermal heat can effectively prevent the formation of gas hydrate.It simplifies ground technical process and reduces investment.Due to the simplified process,the overall and rotation measurements are usually adopted for most gas wells with downhole throttle.Thus,it brings difficulties to single-well dynamic analysis.A production calculation method and its corresponding procedure have been established.Field application shows that the method is feasible and has a certain guidance for production evaluation.
